After you get a nitro, pick up a Titan powerup. Use your nitro for about
half a second and fire the Titan. Continue to hold the nitro for about
1/4 of the second after the Titan is launched. The Titan will now
shoot as fast as a mug missile.

When you find the extra life pick up, you can continue to build up extra lives
by doing the following: Go to the level that has the extra life and pick it
up and then abort the mission (you won't lose the extra life). Repeat this
until you have as many as you want then go to a save area and beat it and
you can save all of the extra lives.

If you beat level 1 in two minutes and 30 seconds or less, you'll go to
the medium difficulty levels branch. Finish Level 1 in one minute and
40 seconds or less and you will go to the hard difficulty levels branch.
There are two other levels in which you can "warp" from the Medium path
to the Hard path. They are "Catch the Orb" and "Power Down" -- (both found
in the Medium path). In Catch the Orb, you'll have to chase down the third
bounty hunter within the game (don't pick up the fake golden orb of
matter) and once you destroy the hunter, he'll drop the real golden orb. Get
it, and return to the starting point -- now you will be able to play the
Hard path. In Power Down, simply make your way to the end of the stage,
(pick up a resnic reanimator -- extra life), hit all three switches, then
destroy the enemies that come out of the now unlocked doors. Once this
is done, the thing in the middle will lower it's protective armor, and then
go to the front of it and blast the Red "eye". (The other way, to remain on
the medium path, is to blast the eye at an angle, while it's armor is still
up. -- best method, is Trojax).

Do you have problems taking out the hovering metatanks? To kill a
metatank without getting hit, go right under it, where it can't shoot you.
Just keep blasting away until it blows up. Be careful though, the explosion
damages your craft, so back away when the tank is almost dead.

There are eight secret characters in the game, making a total of 16
selectable characters. Their names are Septre, Ex-Cop, Jo, Nubia, Cerbero,
Mephistofun, Hk-5, and Dr. Nepenthe (Nutta). Here is how to unlock them:

Each of the eight characters are located somewhere within the levels
of the single player game. If you find a character, blow them away. After
you successfully kill them, you will be able to select them on the Biker
select screen. If you have unlocked the Battle Mode you can unlock them
by killing them within the eight battle mode levels. Sometimes if you
use CPU opponents in the multiplayer mode, one of these secret
characters will be a CPU drone.

To bypass those ads at the beginning, simply perform the following:
Turn on the N64. Wait for the first opening screen. Press the reset button
on your console. Now you can bypass the opening screens with the start
button. This shaves a minute or so off of what is otherwise an unavoidable
onslaught of ads and company titles.

To change your character while you are between two levels in the single
player mode, go to the main menu, and select multi-player. Select the
character you want, and go back into single player, making sure not to
start a new game. Start a level, and you should have the character.
